Continuing to develop this tech could make it useful for setting up buildings in hostile environments. Initially deserts and the arctic/antarctic.
But eventually using unattended robots to construct structures on the Moon and Mars.
I think the relevant Onion article is this classic from 1998: "New $5,000 Multimedia Computer System Downloads Real-Time TV Programs, Displays Them On Monitor" https://www.theonion.com/new-5-000-multimedia-computer-syste...
20 years later analog TV is long dead. TVs are now computers.
This probably won't add up to much in the next 20 years. But it's early tech and there are exciting long term possibilities.
To add to this: If you've ever been to these embedments after the fact, they can leave behind a lot of waste/trash. Namely, concrete (pads, walls, etc). Much of which cannot be easily re-used and breaking it down is expensive/hard.
You use 80% locally sourced materials, if the base just gets left, and starts to breaks down, all you wind up with is mostly original dirt from the area instead of toxic concrete dust.
PS - Although Hesco barrier[0] has also made very positive inroads here, replacing concrete with mostly local dirt, chicken wire, and fabric. But it cannot be used for dwellings, only perimeter wall.
As far as practicality, I'd be more interested in the long term stability of the material. But you likely can do the same thing we did with my friends earth ship style domes, which was to coat them in fabric and then spray a few mm thick layer of cement all over it.
Here's the result. As you can see this is something that would appeal to quite a few people. Pre COVID he had no problem booking airbnb guests for this every night for months out.

I wouldn't be so quick to be dismissive of this general concept. Particularly in Mediterranean areas where wood framing materials are more expensive, this may a perfectly reasonable approach.
But this approach for building a house on Earth to house humans seems way off the bell curve of potential to scale.
And if you consider that brick houses have bricks made of clay, that's even more...
You realize there are lots of brick houses out there and those things aren't run through the brick walls either right?
2x4 dimensional lumber framing is used inside and those are run through the studs.
Stop with this arrogance, because I can bet that your POC are nowhere near as good looking.
I just cut the wall, run my wires inside and cover with plaster.
Have you seen architecture in like, any warm part of the world, especially Italy? Masonry/concrete techniques dominate.
If anything, this is far easier to integrate with utilities, since it can be incorporated into the 3D design.
It also seems easier to drill through than traditional masonry/concrete.
This technique is even more labor-saving than filling formwork with local materials, because formwork is very labor intensive, and you can't readily incorporate unusual utilities, windows, shapes, etc.
It's pretty hard to beat traditional methods and anything new typically has to be measurably quite a lot better.
If a person wanted to drive down costs, I'd probably tend more towards larger prefab components.
Maybe it's not so different from software in these areas.
If any engineers out there have links to tests or studies please do post them.
In any case, it's an interesting experiment that should provide good data and observations toward a more "complete" house prototype.
